What this means

How to read this graph for Shih Tzu

  • The toy-breed band stays narrow, and the Shih Tzu line sits in a compact middle where calm routines usually keep the trend stable.
  • Coat can soften the outline, so the graph is most useful when you pair it with regular weigh-ins rather than relying on appearance alone.
  • Use the calculator after each checkpoint and compare it back here whenever meal size, treats, or movement changes start to stack up.

When to re-check

<16 w weekly | 16-32 w biweekly | 32 w+ monthly

Smaller breeds usually settle earlier, so tighter early check-ins help more than long gaps.

FAQ

Frequently asked questions

Shih Tzu dogs usually land somewhere around 4-7 kg (8.8-15.4 lb), but frame and routine still create normal variation.

Re-check a Shih Tzu every 2 weeks during the active stages, then monthly once the line looks settled.

For Shih Tzus, the main priority is preventing slow extra gain. Calm routines, measured meals, and body checks under the coat keep the estimate honest.

Puppy growth is not linear. A range leaves room for normal variation in frame, activity, and routine.

Use the calculator when you know age and current weight, then compare that result with the matching size chart for added context.

Keep monitoring trend direction. Activity changes, meals, and treats can temporarily move the estimate without meaning the long-term path is wrong.

Talk to your vet if your Shih Tzu loses normal appetite, starts trending upward despite controlled feeding, or looks harder to assess because coat and frame are changing together.
